Home - Holy Union Sisters

At the heart of who we are is our name, Holy Union

We express this union first of all by being one with ourselves. We strive to bring this union to our world by working among different cultures, ethnic groups, the deprived and marginalized. We strive to respect and care for the earth.

The Holy Union Sisters are an international congregation of Catholic women religious who minister today on four continents. We wear a cross with the Latin words, Sancta Unio inscribed on the front, as a symbol of our internationality. It reminds us of the desire of our founder, Jean Baptiste Debrabant, who in a letter to the sisters in 1842, wrote of the special significance of our name: “You have received that name only that you may form all together a union of heart, mind and affection in Jesus and Mary.”
